SLAC ILC and the GDE

• Snowmass ILC meeting was very effective
• Working and Global groups developed baseline
  recommendations
• SLAC had a strong presence
• Roughly 40 people from SLAC for the ILC
  Accelerator
• Many Working or Global group co-leaders were from
  SLAC
• GDE was formed with an initial complement of 49
  people
• Five (or six) people from SLAC representing a
  breath of experienceChris Adolphsen, Tom Himel,
  Tom Markiewicz, Nan Phinney, myself
• Now 62 people including Ewan Paterson, Pantaleo
  Raimondi, Marc Ross, Andrei Seryi, John Sheppard
  plus PT in March
• Next phase is beginning
• Develop the Reference Design Report (RDR) in CY06
• Strong RD program to be coordinated by the GDE
• Gerry Dugan is developing American regional plans

GDE Organizational Evolution for RDR

• Selected additions to the GDE following the BCD
  completion having needed skills in design,
  engineering, costing, etc
• Change Control Board
• The baseline will be put under configuration
  control and a Board with a single chair will be
  created with needed expertise.
• Design / Cost Board
• A GDE Board with single chair will be established
  to coordinate the reference design effort,
  including coordinating the overall model for
  implementing the baseline ILC, coordinating the
  design tasks, costing, etc.
• RD Board
• A GDE Board will be created to evaluate,
  prioritize and coordinate the RD program in
  support of the baseline and alternatives with a
  single chair

7
Change Control Board (CCB)

• The Change Control Board is responsible for
  maintaining the baseline configuration as defined
  in the Baseline Configuration Document.
• The first action of the CCB will be to finalize
  the BCD and put it under configuration control.
• In addition to maintaining the baseline, the CCB
  will assess RD projects defined in the BCD that
  potentially can lead to improvements over the
  baseline in cost or performance.

Nobu Toge (chair)

Design Cost Board (DCB)

• The Design / Cost Board will be responsible for
  assessing and providing guidance for the overall
  RDR design effort program.
• The DCB initial goals will be to propose the
  overall structure and content for the RDR
  document to be developed by the end of 2006.
• The DCB will set goals and milestones for
  producing the RDR, conduct design reviews and
  provide guidance and assessments of the RDR
  effort.

Peter Garbincius (chair)
9
Global RD Board (RDB)

• The Global RD Board will be responsible for
  assessing and providing guidance for the overall
  RD program. 
• The RDB will suggest priorities for the research
  facilities and RD supporting the baseline, the
  RD on alternatives to the baseline and selective
  RD that could further the field in the longer
  term. 
• The RDB will develop a proposal driven program,
  structured to allow comparison across different
  regions and national funding systems.

Reference Design Matrix

• Area systems leaders are responsible for
  design and cost
• Technical systems are to provide engineering
  and costing
• Global systems have support and design roles

SLAC ILC 2006 Program

• Roughly equal division between support for the
  RDR and the RD program
• Elements of the RD program
• L-band test facility in ESB
• Coupler test stand and L-band NC structure
• Marx generator modulator
• Concept demonstration and installation in ESB
• ATF2 final focus system
• Kickers, magnets, movers, BPMs, and power
  supplies
• Machine-Detector Interface studies at ESA
• Collimator wakefield, spectrometer studies
• Secondary Electron Yield
• Projects at PEP-II and maybe KEKB
• Instrumentation development
• Many projects at KEK and DESY

New ATF Extraction Kicker
Refurbished SLC kickers for ATF Shipped July 05
and installed Oct 05 300 ns long pulse to prep
ATF for ILC-like beam extraction
15
Secondary Electron Yield(Damping Ring
Instabilities)

• Test chambers being constructed for
  installationin PEP-II in 2006
• Test different samples inreal environment
• Test grooved chambers asa potential solution

Linac Design

• Rf Sources and Structures
• Klystrons, modulators, rf distribution, and
  couplers
• Building NC rf structures
• Quadrupole alignment
• Use a SC linac quadrupole from DESY to study
  shunting alignment ability very important to
  achieve desired tolerances
• Continue program for NC quadrupoles
• Diagnostics
• BPM development (program with TTF, ATF and LCLS)
• Laser wire development (program at ATF and
  PETRA3)
• Cavity diagnostics (program at TTF)
• Measure vibration due to SC cryogenic equipment
• Important for conventional layout and BDIR

• Good progress on the Marx Generator modulator
• Modular system for lower cost and greater
  availability
• High voltage operation to simplydesign and linac
  tunnel

18
Klystrons (RF Power Generation)

• Three industrial vendors for baseline 10MW MBK
  tubes
• Still little real experience with multi-beam
  klystrons
• Thales has delivered two (3?) refurbished tubes
  to DESY
• CPI 10MW tube was accepted by DESY may come to
  SLAC later
• Toshiba 10MW tube has also been accepted
• All 10 MW MBK tubes are having problems
• Three elements to SLAC program
• Develop L-band sheet beam klystron (funded by
  Accelerator RD)
• Consider alternate power sources (5 MW tubes,
  gyrotrons, )
• Buy L-band rf power at SLAC (needed for
  experience and other elements of program)
• Possibly work with DESY and CPI on CPI 10 MW tube

19
High Resolution BPMs
